Therefore, we examined if the embryo reduction technique can resolve the CEP without any complications while conserving the patient\u2019s fertility. We report three cases in which CEP didn\u2019t respond to MTX but was successfully solved by embryo reduction. Each patient underwent a standard in vitro fertilization (IVF) protocol. Once CEP was confirmed, the pregnancy\u2019s location, the fetus\u2019s size and gestational sac and heartbeat were determined. Afterward, embryo reduction was performed under general anesthesia (operative time: ~30\u00a0min). All patients had successful procedures without any postoperative complications. Since the procedure, one woman was pregnant and delivered, the second has registered a positive \u03b2-human chorionic gonadotropin test and the last is waiting for IVF preparation. In summary, embryo reduction is a feasible approach in the management of CEP with favorable fertility outcomes.<\/jats:p>","DOI":"10.1093\/jscr\/rjab216","type":"journal-article","created":{"date-parts":[[2021,5,10]],"date-time":"2021-05-10T11:31:07Z","timestamp":1620646267000},"source":"Crossref","is-referenced-by-count":6,"title":["Successful management of cervical ectopic pregnancy with embryo reduction: report of three cases"],"prefix":"10.1093","volume":"2021","author":[{"given":"Ginna","family":"Ortiz","sequence":"first","affiliation":[{"name":"Investigaci\u00f3n Cl\u00ednica, Instituto de Infertilidad y Gen\u00e9tica M\u00e9xico SC, Ingenes, M\u00e9xico City, M\u00e9xico"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Nicolas","family":"Kameyama","sequence":"additional","affiliation":[{"name":"Investigaci\u00f3n Cl\u00ednica, Instituto de Infertilidad y Gen\u00e9tica M\u00e9xico SC, Ingenes, M\u00e9xico City, M\u00e9xico"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jean Paul","family":"Sulaiman","sequence":"additional","affiliation":[{"name":"Investigaci\u00f3n Cl\u00ednica, Instituto de Infertilidad y Gen\u00e9tica M\u00e9xico SC, Ingenes, M\u00e9xico City, M\u00e9xico"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Esther","family":"Lopez-Bayghen","sequence":"additional","affiliation":[{"name":"Departamento de Toxicolog\u00eda, Centro de Investigaci\u00f3n y de Estudios Avanzados del Instituto Polit\u00e9cnico Nacional (CINVESTAV-IPN), M\u00e9xico City, M\u00e9xico"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"286","published-online":{"date-parts":[[2021,5,27]]},"reference":[{"key":"2021070811442131600_ref1","doi-asserted-by":"crossref","first-page":"hoz028","DOI":"10.1093\/hropen\/hoz028","article-title":"Management and reproductive counseling in cervical, caesarean scar and interstitial ectopic pregnancies over 11 years: identifying the need for a modern management algorithm","volume":"2019","author":"Shah","year":"2019","journal-title":"Hum Reprod Open"},{"key":"2021070811442131600_ref2","first-page":"130","article-title":"Methotrexate for cervical pregnancy.
